SPECIFICATION forming part of Letters Patent No. 760,411, dated May 24, 1904:.

Application filed November 16, 1903- Serial No. 181,263. We model.)

1'0 0.6L w/wm it may concern.-

Be it known that I, CnAaLns Action), of the city, county, and State of N cw York, have invented a new and Improved Vise, of which the following is a full, clear, and exact description.

My invention relates to improvements in Vises of the kind generally attached to a bench or other support to secure various articles in order that they may be worked upon to advantage; and the object of my invention is to produce a vise having a greater adaptability than is usual in tools of this class.

My invention is intended to provide opposed jaws moving as usual in relation to each-other and to construct the jaws in such a way that various articles can be conveniently gripped by them; also, to provide for holding in the main jaws a pair of supplemental jaws which are adapted to adjust themselves to surfaces which are not parallel with each other, and,-

further, to arrange the instrument so that the jaws and the article which they grip can be swiveled in relation to the base of the vise and fastened in any desired position.

My invention also comprises certain other details of construction, which, together with other advantages, will hereinafter appear.

To these ends my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of a vise embodying my invention. Fig. 2 is a plan view of the main jaws with the supplemental jaws attached. Fig. 3 is a view similar to Fig. 2, but showing the supplemental jaws of a slightly-different shape. Fig. 4: is a detail section on the line 4 4 of Fig. 3, and Fig. 5 is a perspective view of one of the supplemental jaws.

The vise has a base-yoke comprising the parts 10, 11, and 12, of a generally U shape and forming, in connection with the thumbscrew 13, a clamp by means of which the vise may be secured to a bench or other sup port. The members 10 and 12 of the thumb or clamp are parallel, as is usual in viscs, and the thumb-scrcw 13 has preferably a widened inner end 14, adapted to grip the bench or support to which the clamp is fastened.

The vise is provided with a base-plate 15, which is of the same general shape as the member 10 of the fastening-clamp, except that it is longer, and the parts 10 and 15 are preferably widened near the center, as shown at 10 and 15, at which point the aforesaid parts are pivoted together, as shown at 16, so that the base-plate,which carries the working parts of the vise, may be turned on the pivot in order that the vise may be brought to a desired position. The parts 10 and 15 are pierced by numerous holes 17, and a pin or pins 18 can be thrust through the holes when they are brought into registry, so that the parts may be fixed temporarily in relation to each other.

At one end. of the base-plate 15 is a fixed jaw 19, of the general shape of ordinary visejaws, having its upper end curved inward and broadened, as shown at 19, and opposite the fixed jaw is a sliding jaw 20, also curved at its upper end, as at 20, these curved and broadened portions serving to grip an article in the usual manner. ()n the back of the movable jaw is produced an anvil 21, on which articles may be hammered and shaped as usual. The jaws are moved in relation to each other by the customary screw 22, having the usual handle 23, the screw turning in the fixed jaw and engaging the corresponding thread in the movable jaw, and in order that the thread may be protected from iron-filings or other debris the Screw is covered on its upper side by a housing 24, which is secured, to the fixed jaw and extends through a suitable hole in the movable jaw. The movable jaw is guided on a rib 25, which is T-shaped in cross-section and which is fast on the base-plate 15.

The jaws, or rather the gripping portions 19 and 20 of the jaws, canbe provided with various recesses to assist their holding qualities, and I have shown the following as being likely to have extensive use: The recess 26 extends across the entire face of each jaw to enable a rod to be conveniently gripped, and a squared recess 27 is arranged vertically in each jaw, so that a flat article can be gripped to advantage. It is often desirable to hold a screw in a vise in such a way that the head will not be injured. To this end I provide vertical opposed recesses 28, extending down ward from the upper edge of each jaw and merging into recesses 28 (see Fig. 1) of the general shape of a screw-head, so that by placing the head in the recesses 28 and the shank of the screw in the recesses 28 the screw may be held without injury.

To provide for holding articles which are of unequal thickness on opposite edges, I use the supplemental jaws 29 and for gripping curved surfaces the supplemental jaws 30. (See Figs. 2 and 3.) These jaws are alike in their general construction; but their opposed surfaces are difi'erently shaped, the jaws 29 being plain and the jaws 30 being slightly concave and provided with teeth. 29 or 30, as the case may be, has centrally on the back a horizontallyprojecting lug 31, u hich enters into a corresponding slot in the block 33, where it is held by a pivot-pin 32. The block 33 is shaped like the segment of a cylinder, the surface next the jaw 29 or 30 being the curved surface, so that the jaw may rock slightly in relation to the block, and the block fits in a recess 34: in the jaw 19 or 20, as the case may be, and it has projecting laterally from opposite sides wings 35, which do not extend the full height of the block and which seat themselves in recesses 36 in the main jaws 19 and 20. This arrangement, it

will be seen, seats the block 33 very firmly in the vise-jaw, and at the same time it permits the supplemental jaws to rock, so as to adapt themselves to the matter which they grip, while it also provides for the easy and quick insertion of the supplemental jaws in the main Each jaw jaws or their removal. hen the supplemental jaws 29 or 30 are not used, the recesses 3a, which extend vertically across the parts 19 and 20 of the main jaws, serve to grip a pipe or rod when it is desirable to hold the same in a vertical position.

In addition to the supplemental jaws29 and 30 I provide pipe-grips in the form of jaws 37 and 38, which are recessed on their opposed edges, so as to grip firmly a pipe-rod or other article placed in them, and to make the gripping qualities better I i use one central jaw 37, which is attached to the fixed main jaw 19, and two of the jaws 38, which are not directly opposite the jaw 37, but are arranged at each side of it, so that there are two gripping-jaws on one side of the rod or pipe to be held and one centrally on the other side. The jaws 37 and 38 have shanks 39, which fit in slots 40 of the main jaws, and they are held in place by suitable pins or bolts 41.

The vise is worked like the ordinary vise, and from the description already given it will be seen that it has a wider use than most vises and can be very quickly and conveniently adapted to the different purposes for which it is intended.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination with the main jaws, of the blocks having lateral wings, the blocks and their wings being arranged to fit in corresponding recesses in the main jaws, and auxiliary jaws pivoted to the blocks.

CHARLES ARNOLD.
